Why is the Top Coat Essential?

If you've ever been frustrated by nail polish chipping too quickly or losing its shine, you'll love this little secret of professional manicures. The top coat is designed to protect and enhance the polish while extending its wear. Whether you prefer chic nudes or deep reds, it has become a must-have in every manicure routine.

Protection and Durability of Nail Polish

The top coat acts as an invisible shield that protects the polish from bumps, scratches, and daily wear. Thanks to its durable formula, it locks in color and strengthens the nail surface to prevent chipping. You can say goodbye to constant touch-ups and enjoy a flawless manicure for longer, even if your hands are active! It’s a true investment in the longevity of your polish, and it’s perfect for keeping your nails looking freshly done for several days.

Shine and Professional Finish

The top coat provides that glossy finish we all love, giving an instant “salon-fresh” effect. It smooths the surface of the polish, making colors more vibrant and uniform, with an ultra-glamorous finish.

With one simple step, your manicure goes from basic to fabulous, and your nails shine brightly, ready to catch the light and compliments!

What's the Difference Between Top Coat and Base Coat?

The top coat and base coat are both essential for a flawless manicure, but they play very different roles. The base coat, applied first, acts as a protective layer between the nail and the polish. It protects the nail from polish pigments, prevents stains, and improves color adhesion. Some base coats also contain nourishing ingredients to strengthen the nails and prepare them for the manicure.

In contrast, the top coat is applied at the final stage to seal and protect the color. It adds a glossy (or matte, depending on the type) finish and extends the wear of the polish by making it more resistant to bumps and wear. In short, the base coat prepares and protects the nail, while the top coat ensures durability and enhances the aesthetic of the manicure.

What Types of Top Coats Should You Choose?

With so many options available, it can be hard to know which one to choose. Here’s a guide to help you understand the types of top coats, their benefits, limitations, and how to use them for the best result possible. 
 

Classic Top Coats

Classic top coats are probably the most commonly used. They are applied as the final layer after the colored polish and dry quickly in the air. These top coats are perfect for daily use and provide long-lasting shine that protects the polish from scratches and wear.

Advantages and Limitations of Classic Top Coats

The main advantages of classic top coats are their ease of application and accessibility. They are great for quick touch-ups and give a shiny finish that enhances the color’s brilliance. They dry relatively quickly, making them perfect for an express manicure.
However, they also have limitations. The wear of classic top coats is generally less durable compared to semi-permanent top coats, as they don’t withstand bumps or water as well. Additionally, their protective effect often fades after a few days, sometimes requiring reapplication to maintain shine and durability.

Semi-Permanent Top Coats

Semi-permanent top coats, often used in professional salons, offer long-lasting wear that can last up to two weeks. They are applied similarly to gel and require an UV or LED lamp to cure. This type of top coat is ideal for those who want a manicure that withstands daily wear, even with frequent contact with water.

How to Apply Semi-Permanent Top Coats

Applying a semi-permanent top coat requires a bit more care than applying a classic top coat. After applying and curing the colored polish under a lamp, the semi-permanent top coat is applied in a thin layer and cured under the lamp. This process helps to securely fix the polish and ensures long-lasting wear.

Removal and Nail Care

Removing semi-permanent manicures is a delicate step, as they do not dissolve with regular acetone-free removers. To avoid damaging the nails, it’s recommended to consult a professional.

After removing a semi-permanent manicure, it’s advisable to nourish and hydrate the nails with oils and creams since this type of product can dry out the nails.

Matte Top Coats

For a more sophisticated and trendy effect, matte top coats are a great option. They transform the natural gloss of the polish into a matte and elegant finish, perfect for a modern, minimalist look.
Matte top coats can be used with any polish color and are especially popular for nail art.

How to Achieve a Matte Effect

Applying a matte top coat is similar to applying a classic top coat. After applying and allowing your color polish to dry, simply add a layer of matte top coat. It removes the shine and leaves a smooth, soft finish. To maximize the matte effect, make sure each layer of polish is completely dry before applying the top coat.


How to Apply Your Top Coat Perfectly?

Applying a top coat may seem easy, but to achieve a professional and long-lasting finish, there are some steps and tips you should know. Whether you're a beginner or an expert in manicure, following these tips will help you get a smooth, shiny, and long-lasting result.

Key Steps for Application

  • Prepare the Nails: Before you start, make sure your nails are clean and dry. Remove any traces of previous polish with an acetone-free remover to avoid drying out your nails. Lightly file and buff the surface for better adhesion.

    Apply the Base Coat: The base coat is a crucial step to protect your nails and ensure better color retention. Apply a thin layer of base coat and let it dry completely before moving on to the colored polish. This protective layer also prevents the color from staining your nails and improves the adhesion of the color.

    Apply the Colored Polish: Once the base coat is dry, apply your colored polish in thin layers to avoid bubbles. Wait for each layer to dry completely before applying the next one for a smooth and uniform result.

    Apply the Top Coat: Once the color is dry, apply a thin layer of top coat from the base of the nail to the tip. Make sure to seal the free edge of the nail by passing the brush horizontally across the end. This will help prevent chipping and extend the life of your manicure.

Mistakes to Avoid

  • Applying Too Thick Layers: This can cause bubbles and uneven drying. It's better to apply several thin layers rather than one thick coat.

    Not Waiting for Full Drying Between Layers: Patience is key to avoid smudging. Make sure the polish is completely dry before adding a new layer or top coat.

    Shaking the Top Coat Bottle: This can create air bubbles in the product. It’s better to gently roll the bottle between your hands to mix the product without introducing air. 

Manicure Tips

  • Use a High-Quality Top Coat: Not all top coats are created equal. Investing in a good quality top coat truly makes a difference for a smoother and longer-lasting finish.

    Hydrate Your Nails and Cuticles: Keeping your cuticles and nails hydrated enhances the appearance of your manicure and extends its wear. Cuticle oil is perfect for this and can be applied daily.

    Reapply Top Coat Every Two Days: To prolong your manicure, apply a fresh layer of top coat every two days. This helps maintain the shine and protects against everyday wear.

    Avoid Hot Water Immediately After Application: Hot water can cause the polish to swell and chip more quickly. Try to keep your hands away from water during the first few hours after application.

Can You Use a Top Coat Alone?

The top coat is primarily designed to be applied as a finishing layer after colored nail polish to protect and add shine. But can it be used on its own, without any colored polish beneath? The answer is yes! A top coat alone can offer several benefits and be used as a treatment to strengthen and beautify bare nails. Here's how to use it this way, along with the advantages and precautions to keep in mind.

Use as a Nail Care Polish

When applied alone, the top coat can act as a transparent polish that strengthens and protects the nail. Some top coats are enriched with beneficial ingredients for nail health. When used without colored polish, they can help protect nails from external aggressions (like water, chemicals, or minor shocks) while providing a glossy, well-groomed finish.

This application is perfect for those who prefer a natural look but still want to maintain a polished appearance. A top coat applied alone is also ideal for individuals with fragile nails who want to discreetly strengthen them. Moreover, the top coat applied alone is easy to remove and reapply regularly, allowing you to keep your nails clean and healthy.


Benefits and Precautions

  • Benefits: Using a top coat alone provides slight protection and a natural shine to the nails. For those who prefer a matte finish, some top coats can create this effect even without colored polish underneath.

  • Precautions: While a top coat alone has benefits, it does not protect the nails in the same way as a specific treatment or hardener. If your nails are very brittle, it may be better to use a product specifically formulated to strengthen them before applying a top coat.

For example, if you're caring for damaged nails, it's better to use a strengthening serum like Poderm's Striated, Brittle, and Split Nails Serum. This natural hardener deeply nourishes and strengthens nails and cuticles damaged by external aggressions.

Additionally, some top coats may slightly yellow over time, especially when applied directly onto the nails without a base coat underneath.
